At this point, we don't know any cast members. And since the only photos we've seen have been of props and a helmeted character, the mystery remains.

Here's the official synopsis: "After the stories of Jango and Boba Fett, another warrior emerges in the 'Star Wars' universe. The Mandalorian is set after the fall of the Empire and before the emergence of the First Order. We follow the travails of a lone gunfighter in the outer reaches of the galaxy far from the authority of the New Republic."

The show is set to premiere on Disney's upcoming streaming service sometime in late 2019.
